[Penile gangrene: a rare complication of systemic calciphylaxis, to be screened].

Gangrene of the penis is a rare and serious complication of end stage renal disease, being an expression of systemic calciphylaxis. We report the case of a 58-year-old patient with chronic renal failure and diabetes, who presented with a necrosis of the gland. MRI defined the limits of necrosis. The treatment consisted in partial amputation of the penis. Histological examination found a calciphylaxis.
